mythtv-vid: X11 Video output fixes branch

[danielk]

The point of the mythtv-vid branch is to fix some of the long standing deficiencies in the video output classes, for X11 in particular:

Filters

• Add OpenGL Lanczos filter
• Make setting up filters easier with a GUI
• Allow changing the filter set during playback, esp for deinterlacing.
• [DONE] Add support for OpenGL filtering for scaling and YV12->RGB conversion for display
• [DONE] Allow different filter sets for different video and display resolutions.
• [WONTFIX, see #1778] Auto-detect pull-up and apply ivtc filtering

Video output methods

• Implement per-frame video resolution switching
• Support XvMC for MPEG-2 NUV files (and enable transcode to MPEG-2)
• Key xrandr switching to video framerate
• [WONTFIX, VDPAU much more promising] Finish support for XvMC copy to pbuffer + opengl render

OSD rendering

• Fix video frame OSD blending for bob-deint (Filter vert freq in pause + when there is video<->screen framerate mismatch)
• Implement RGB OSD surfaces
• Implement X Composited OSD surfaces
• [DONE] Implement OpenGL OSD surfaces
• [DONE] Key preferred OSD and OSD fade to resolution and video output method.

There remain problems with the PlaybackProfileConfig loading and saving, especially with respect to new configs.

Instead of hard coding the disabling of the OSD fade for XvMC and HDTV this changeset makes this a controlable properlty of the video display profile, so you can enable fading when you have a fast GPU or CPU.

If you were already using the mythtv-vid branch, I recommend dropping the displayprofilegroups and displayprofiles tables. Otherwise this property will not be configurable.

Changing channels to new tuner ignores channel and defaults to stored cardinput.startchan instead with no indication of selected channel in log nor any lines stating it being bad. Tuning from there to desired channel works. I changed from channel 244 to 122 and mythbackend selected the stored channel 9429:

(In [13548]) Refs #2287. Refs #2649. Fixes a bug in XvMC-OpenGL introduced by [12708].

We changed to using glTexSubImage2D() to fill the OSD texture, but we're losing the alpha so it covers up the video. This changes back to using glTexImage2D().

[danielk]

(In [13549]) Refs #2287. Fixes bug in XvMC-OpenGL pause handling.

The XvMC-OpenGL video renderer stopped updatating the OSD once the video was paused because PrepareFrame was doing the compositing step. This changeset moves the compositing step to the Show() method so that the OSD is still updated when the video is paused when using the XvMC-OpenGL video renderer.

[danielk]

(In [13769]) Refs #2287. Workaround for an apparent nvidia bug that caused blank screens after video rendering method changes.

The problem was noticed by Stanley Kamithi and worked around by Mark Kendal. The video playback window would be blank when switching from OpenGL to XvMC rendering with 8776 and crash when using the 9755 drivers, This may have something to do with the change to using the 3D pipeline to emulate XVideo in the newer drivers. The workaround was simply to unmap and map the subwindow with the OpenGL context instead of deleting and recreating it as we switch between rendering methods. The window and context are still properly deleted when we delete VideoOutputXv at playback shutdown.

[matt.doran@…]

As requested by danielk, when enabling the hardware deinterlacing I see errors in the log like this:

2007-06-28 23:45:15.560 VDP: GetFilteredDeint() : -> 'opengllinearblend' 2007-06-28 23:45:15.564 FilterManager: failed to load filter 'opengllinearblend', no such filter exists 2007-06-28 23:45:15.564 Couldn't load deinterlace filter opengllinearblend 2007-06-28 23:45:15.564 Using deinterlace method 2007-06-28 23:45:15.564 SetVideoRenderer(opengl)

This might be expected, because it's doing the deinterlacing in the hardware rather than the software filter ... but it's a bit misleading and will probably cause some confusion.

[danielk]

(In [14057]) Refs #2287. Some tweaks to videodisplayprofile. This removes the 'last_video_renderer' check in SetVideoRenderer(), if LoadBestPreferences() has been called since SetVideoRenderer() was last called the preferences for the deinterlacers, osd renderers, etc may no longer be compatable with the video renderer, so we need to recheck this.

This also adds some debugging output and names the quartz-accel OSD renderer.

[danielk]

(In [14058]) Refs #2287, Moves myth2av_codecid from videoout_xv.cpp to mythcodecid.cpp, and adds DVDV codecs to mythcodecid. This is in preperation for using myth2av_codecid in videoout_quartz.cpp

[danielk]

(In [14060]) Refs #2287. Fixes a regression in the ability to enable deinterlacing.

Basically the SetScanType() just ignored any attempts to enable deinterlacing because we removed the m_DeintSetting from NuppelVidepPlayer and didn't replace it with anything now that the video renders track the deinterlacing settings.

[danielk]

Patch to add OSX DVDV decoding (not functionning).

[danielk]

(In [14062]) Refs #2287. Removes hard coded "bobdeint" for XvMC deinterlacing.

The deinterlacing method can now be controlled for XvMC again, you have two options "oneline" and "bobdeint".

[danielk]

(In [14063]) Refs #2287. #1279. This applies an updated version of DVDV code to libavcodec.

John Dagliesh wrote the original DVDV code and Nigel did the original merge, see #1279, this just updates the merge to work with the latest changes in how ffmpeg handles codecs and commits the mpeg12.c and dvdv.c portions of the patch.

you need to rerun ./configure before recompiling (to pick up the new codec define.)

[danielk]

(In [14064]) Refs #2287. Changes ./configure to enable XvMC OpenGL support by default if you explicitly link to libXvMCNVIDIA. It is still only used if you enable it in your display profiles.

[danielk]

(In [14065]) Refs #2287. Reverts everything but ./configure change in [14064], I accidentally committed a bunch of extra code from another patch.

[danielk]

(In [14068]) Refs #2287. This makes 3 changes to the VideoOutput::InputChanged() and a complimentary change to VideoOutput::Create().

The main change is to add a new param "codec_private". The OS X DVDV playback renderer needs access to the DVDV decoder which is created in AvFormatDecoder. This allows this data to be passed to VideoOutputQuartz in a generic way which we could reuse in the future without changing the InputChanged() signature again.

The two smaller changes were things I've wanted in the API for a while, but were too trivial to make the API change for alone. The changes are to: (1) return a ok/failed status from InputChanged(). Changing the resolution of a video can fail if the resolution exceeds what the hardware is capable of, as in #3680. In [14009], I was able to check the error status after calling InputChanged() to avoid the segfault. But actually returning this information is much nicer API wise. (2) The other is to use a QSize for the dimensions of the video, this avoids us needing to convert from QSize to ints and back to QSize when calling InputChanged().

Finally, VideoOutput::Create() just had the "codec_private" paramater added so that we can pass the initial information in when creating a VideoOutput instance. This wasn't added to VideoOutput::Init() since we can just pass the codec_private into the constructors that need it and keep the changeset much smaller.

[danielk]

(In [14069]) Refs #2287. Restores ApproveDeintFilter() check in VideoOutput::SetupDeinterlace().

ApproveDeintFilter() got in the way of testing the display profile code, but is still needed when no matching profile is found for a particular video.

[danielk]

(In [14070]) Refs #2287. Refs #3523. Various minor fixes to VideoOutputQuartz.

• Changes QuartzData from a struct to a class, so we can properly initialize all it's variables without an init function.
• Sets data pointer to NULL after deleting the class for easier debugging.
• Calls SetVideoRender() in the ctor and CreateQuartzBuffers(), the latter is needed in case there is no quartz video profile, otherwise the VideoOutputBase::Init() call may reset the renderer.
• Sets display_dim and display_aspect properly. This is a prerequisite to addressing #3523,
• Removes incorrect code in VideoOutputQuartz::GetAllowedRenderers() for enabling DVDV rendering.
• Tidys up some VERBOSE macros.

[freedenizen@…]

I noticed that Vertical Scaling doesn't appear to be honored by the opengl renderer. I haven't had a chance to test the other overscan options to see if they work or not.

[danielk]

(In [14095]) Refs #2287. Updates DVDV hooks for mythtv-vid branch.

This is disabled by default and Nigel is the only person to have gotten this change to work partially (i.e. with a couple bad crashes.) But it's there for you to try using the "--enable-dvdv" ./configure flag..

[danielk]

(In [14096]) Refs #2287. Reformats videoout_dvdv.{h,cpp} in MythTV convention and comments out NSAutoreleasePool code that was causing a segfault. (The NSAutoreleasePool will be dealt with in a seperate changeset.)

[danielk]

(In [14098]) Refs #2287. Creates and destroyes the memory allocator needed by Cocoa.

The OS X Cocoa libraries assume that you have a garbage collector allocated and will leak memory if you don't. However it needs a specific garbage collector for each thread which creates some complications. This creates and destroyes the garbage collector needed to handle DVDV stuff.

We really should allocate a garbage collector for each thread in MythTV on the OS X platform, but this addresses the only major memory leak this Cocoa requirement appears to cause. And addresses all the additional memory leaks DVDV could have added to the mix.

[danielk]

(In [14113]) Refs #2287. Disables video preview in EPG when you use OpenGL video renderer.

This is a patch from Mark Kendal, The OpenGL rendering method doesn't support video preview in the EPG so we don't want to waste the screen real estate on it.

[danielk]

(In [14255]) Refs #2287. Sets the myth binary revision and protocol revisions to numbers that don't conflict with trunk.

This requires plugins to be rebuilt. Basically some of the reports in the mythtv-vid testing threads were caused by not recompiling plugins for mythtv-vid or using a mythtv-vid frontend with a non-mythtv-vid backend this should prevent this type of problem for testers.

You must rerun ./configure before comiling and recompile and install the plugins after installing this.

Unlike the mythtv-vid branch, compiling OpenGL rendering is disabled due to some instability issues.

There are a few video related things in here:

• Adds Video Profiles and a Video Profiles Editor to Playback config. This allows you to use different rendering methods and deinterlacer options for different video resolutions.
• Adds an accelerated playback "DVDV" for OS X
• This enables compiling XvMC chromakey rendering by default
• This enables compiling DirectFB rendering by default, and adds support for the newish DirectFB 1.0
• This enables compiling PVR-350 rendering by default
• This splits OSD configuration out from the general Playback config. (A separate commit will add this to the external themes.)

Please report any problems on the #2287 mythtv-vid ticket.

Hi.

• There's a typo in ./configure --help output:

    --enable-opengl-video   disable opengl based video display
  

should probably read "enable opengl based video display".

• When editing the video display profile, I can select osd renderers/decoders which were not actually compiled in. Of course, it falls back to sane defaults and lets me watch TV, but it might be better not to display choices which were not compiled in. Just a thought.

Hi,

I'm using an interlaced PAL modeline to drive my TV:

Modeline "720x576pali" 13.88 720 726 794 880 576 580 583 625 -hsync -vsync interlace

My video/osd render method is opengl. When i'm trying to use the normal (software) bodeint, i get the following messages:

2007-09-07 15:44:48.131 VDP: GetFilteredDeint() : opengl -> 'bobdeint'
2007-09-07 15:44:48.132 VDP: GetFilteredDeint() : opengl -> 'bobdeint'

2007-09-07 15:44:48.134 Couldn't load deinterlace filter

However, the hardware bobdeint works:

2007-09-07 15:42:36.081 VDP: GetFilteredDeint() : opengl -> 'openglbobdeint'
2007-09-07 15:42:36.081 GLVid: Creating openglbobdeint filter.

2007-09-07 15:42:36.092 GLVid: Turning on deinterlacing.

Prior to the mythtv-vid merge, bobdeint would never work for me because my refresh rate was too low. I had to use the patch from #2903 to enable bobdeint (without a deinterlacer, I would get interlace artefacts/stuttering despite my video resolution matching my display resolution - same happens to a lot of other people, too). Now I'm kinda confused by this discrepancy - is it intentional that openglbobdeint works while bobdeint does not?

I should note that I'm using a Twinview setup. CRT-0 is a 19" CRT monitor running at 1280x102, CRT-1 is my TV running said modeline.

• Allows OpenGL rendering to work with GLX 1.2 for ATI and Intel cards.

• Adds a new OpenGL video renderer output filter from Mark Kendall.
• Reworks some of the OpenGL video renderer locking for greater stability.

Replying to danielk:

(In [13769]) Refs #2287. Workaround for an apparent nvidia bug that caused blank screens after video rendering method changes.

The problem was noticed by Stanley Kamithi and worked around by Mark Kendal. The video playback window would be blank when switching from OpenGL to XvMC rendering with 8776 and crash when using the 9755 drivers, This may have something to do with the change to using the 3D pipeline to emulate XVideo in the newer drivers. The workaround was simply to unmap and map the subwindow with the OpenGL context instead of deleting and recreating it as we switch between rendering methods. The window and context are still properly deleted when we delete VideoOutputXv at playback shutdown.

This Bug, or something similar, seems to be appearing with the latest (beta) Drivers from Nvidia. Closing and reopening the Internal Videoplayer causes an blank Screen.

Fix a locking problem introduced by [19042], basically the commBreakMapLock is non-recursive so it was being locked twice by NVP::AutoCommercialSkip() after I added a missing locking in NVP::ClearAfterSeek() which was being called with and without a lock being held but calls SetCommBreakIter() which requires the lock to be held. Now ClearAfterSeek is only called when the lock isn't being held.

(In [19129]) Refs #2287. Converts most of the event loop in the TV class to Qt timer events.

Five untriggered events remain, two need to be initiated by nvp actions, two I don't understand the code well enough, and one I just haven't looked at yet. I'm only checking these remaining untriggered events every 250 ms rather than every 50 ms; since all the stuff that needs to be snappy is now triggered immediately.

The code in tv_play.cpp still needs to be made pretty, more refactoring into PlayerContext is required, and this is probably buggier than yesterday's code, but it's on it's way to being better. The UI feels significantly snappier than it did a week ago.

[danielk]

(In [19182]) Refs #2287. Some VDPAU tweaks for the mythtv-vid branch.

Note there are still some problems

• Resolution changes are not handled by the VDPAU code
• VDPAU is treated as a subset of XVideo, videout_xv.cpp may be simpler if it is treated as a subtype outside of the XVideo range.
• All the other known problems, color in OSD, quality of MPEG-2 decoding, etc.
